IMPROVEMENT IN SEAL-LOCKS.

Specification forming part of Letters Patent No. 92 ,768, datedSeptember 4, 1875.

July 3, 1877; application filed my improved lock as applied to andarranged for sealing a car-door. 'Figs. 3, 4, and 5 are, respectively,perspective views of the hooded handle, the lock, and the hasp,separated from each other, and from the car. Figs. 6 and 7 are likeviews of the sealing-key. Fig. 8 is a perspective view of the rear sideof said look.

respectively, perspective views of the front and rear sections of thecasing of said lock separated from each other. Fig. 11 is a like view ofthe spring-latches employed for locking the sealing-key in position, andFig. 12 is a vertical central section of said lock, hasp, andsealing-key in position upon a door.

Letters of like name and kind refer to like parts in each of thefigures. i

The design of my invention is to simplify and render more efficientdevices which are employed for locking and sealing railroadcars, for thepurpose of preventing their contents from being tampered with withoutsuch fact being made apparent; to which end it consists, principally, ina device for sealing cars in which the hasp is provided with two or moreopenings for engagement with the lock, so as to enable the car-door tobe locked and sealed in a closed or in a partially-open position,substantially as and for the purpose hereinafter shown.

It consists, further, in the combined hood and handle employed formoving the door, and for shielding the sealingkey from rain and snow,substantially as is hereinafter set forth.

In the annexed drawings, A represents the side of a car or itsdoor-post, and B a door, which is arranged to slide edgewise over oraway from the doorway.

Secured to or upon the outer face of the door B, near one of its sideedges, is a lock, which consists of an outer plate, 0,, having the formshown in Fig.9, and a housing, 0, (shownin Fig. 10,) that is securedupon the. inner face of said plate.

At the center of the housing 0 is provided a round opening, a, whilewithin the plate 0, in a line with said. opening 0, is formed a secondopening, 0, that corresponds therewith in size and shape.

. Within the housing 0 is placed two blocks, D, which loosely till thespace horizontally,

while vertically said blocks have each about one-fourth of an inch play,and are held in a central position by means of a spring, E,'that isplaced between the outer end of each and the contiguous end of saidhousing.

Within the inner end of each block or latch D is provided a V-shapednotch or groove, 01, which increases in depth and width from front torear, as seen in Fig. 11.

Pivoted at one end, to or upon the outer face of the door-post A, is ahasp, H, which is provided with two or more longitudinal slots, f, asseen in Fig. 5, each of which slots corresponds to, and is capable ofpassing over, a boss,'c, that is formed upon the outer face of thelock-plate O, surrounding the opening 0. When the inner of said slots isin engagement with said boss, the next outer slot passes over aneyebolt, G, which passes inward through said lock-plate and the door,and, when said haspiis in place, receives a pin, H,

' as seen in Fig. 1.

In orderthat the hasp F may be locked in place, so as to prevent thedoor from being opened Without detection, a sealing-key, I, (shown inFigs. 6 and 7,) is employed as follows:

The key I consists of a round shank, which loosely fills the openings 0and a, and a head, I, that is flat and thin, and has such size as tocause it to extend over the outer face of the hasp F upon the upper andlower sides of the openings f.

Near the inner end of the keyshank is formed a shoulder, t, whichengages with the latches D as said key is inserted within the lock, andprevents the withdrawal of the former from the latter.

When the sealing-key is in place over the hasp, as shown in Fig. 1, thelatter cannot be disengaged from the look without breaking from said keyits head or seal, to facilitate which breakage the shank of said key isreduced in size near its junction with said head.

After the seal or head is broken from the shank the latter may beremoved by being pushed inward through the lock.

In order that the lock may not be detached from the door when the latteris locked, one of the four fastenings which pass through said parts isplaced directly beneath the hasp, and is only accessible when the latteris removed from engagement with said look, while a second fasteningconsists of the eyebolt G, which passes through said lock and door, andis prevented from being turned by the engagement of said hasp.

In winter the seal might become obstructed by ice or snow, so as tointerfere with the operation of the device unless suitable protectionwas furnished. Such protection is afforded by a handle, K, which issecured to the door B, directly above the lock 0, and at its lower endis provided with a hood is, that flares outward and downward, and formsa covering or roof for the boss 0, the projecting portion of thesealing-key I, and the slotted portion of the hasp F, which engages withsaid boss.

By this means rain and snow are prevented from falling upon said parts,and much trouble and annoyance are avoided.

In addition to the use named, the handle K is useful for moving the doorB, its location being most convenient for such purpose.

Having thus fully set forth the nature and vided with the hood k at itslower end, sub-.

stantially as and for the purpose set forth.

In testimony that Iclaim the foregoing 1 have hereunto set my hand this24th day of August, A. D. 1875.
